To all whom t may concor/n.:

Be it known that LROBERT C. CAUGHEY,

Illinois, have invented certain new and use.-

p 'ful Improvements in Implement Frames, of

which the following is a specification. l

Hy invention relates to improvements In implement frames in general but has particular application to frames of plows of that type in which disks instead of the usual vnrtype of'bottoms are employed.

' The principal lobjects of the invention are to provide a frame ofthe class described in Iwhich -the spacing of the earth-turning devices'may be adjusted, to suit the various conditions encountered 1n practice and also to' suit the particular type or size of bottom whichis employed; to provide a construction in' which Athe bottoms or disks may be individuallyadjusted both as to depth and inclination; 'to' provide an arrangement of the class described'injwhich where a disk plow is used' the weight is concentrated over the disks, thereby preventing' the latter from climbing and causing the same to move in the desired path; to provide an arrangement Vof the classdescribedwhichis of particular service in connectionwith power lift plows of the fixedv frame type to providea construction'which may be manufacturedfrom 'j matgrial'sr'eadily 'procured in the open market and in general to provide a simple, ef ficient and inexpensive construction of the type referredto.

Referring tothe drawings, it will be seen that the plow is lof the thr-ee-wheel-type in K which the ybottoms are fiXedly mounted upon a single main frame which i-scapable of being elevated or lowered bodily to cause the `bottoms to enter or'loavethe Ygrounds""'The lifting mechanism may be Vof any'desired type, although I prefer 'to use in connection with this invention 'a lifting mechanism as set forth in my application for United States `Letters APatent l\To.Q42,965, filed` July 31, 1915. f

vIn such a type of lifting mechanismk the power forefl'ecting vertical movement of the frame is secured through the'ifrotary movementof one of thefront wheels lland 12 of the plow, sai'dyrotary movement throughjsuitable clutch mechanism serving to rock thearms oraXles 413, 14 in the frame 15. Preferably the same power lis employed toeffect asimilar verticalmovement of the rear endof the frame with respectto the rear wheel 16, a rod l17 connecting'thefront 'power'Y lifting mechanism with the particular mechanism by which said vrear end of the plow is'y elevated or'depress'ed. y

Said ylatter mechanism in thepresent instancecomprisesV a bell-crank leverl18 pivoted onY a lcollar or block 19 rigidlysecured on the'uppe'r end of the rear axle 20, the horizontal arm of said bellcrankfbeing connected by a link 21.to the rear. end22 of the plow frame. Said rear portion '22 ofthe plow frame is suitably lapertured:tolform a guide inrwhich thevertical portion ,2O of In the drawings, which illustrate a rpre-"the aX'le may slide when the .actuating rod ferred embodiment of my invention,

"The framebeam 25 is atV its 'front end bentV obliquely as shown ffa'tf27,"itsffront end'pbeing secured by any suitable kmeans such as bolts j or :rods to the '5 side of vthe. framjefbeam V24. -Theframe *beams 23, 24' and 25 areitted with; angle Vbrackets 28, 29 and 31Hhavinghorizontal up- 'per` .flanges .to whichlmayj be secured @as by "fr bojlts'r 32, the horizontal liange of antangle Y "iron'box' frame33:2y Spaced from the' said box trame ,33`is a complementary parallell similar box` trame 34 which may be secured to the trame beams by bolts 35 and 36 passing through the bentprear ends 37 and 38 ot. the'said trame beams and 24. Prefer!` Iably the apertures through which the bolts 35 and 36 pass are enlarged or slotted to ermit a slight amount ot movement or adjustment of the trame 34 to or from the A i companion box trame 33.

The framemembers33 and 34 which exj tendobliquely across the center line of the disk plow serveas guidesAA or supportsl for the castings 39,V 40, 4l'and 42 which serve l as vertical guide boxes or supports for the encloseduupper ends of the vertical stub beams 43.V As shown best in Figs. 6, 7 and i8, each of Ysaid castings or boxes is substancentrally and vertically slotted or cored out d f heights of? the Stub beams;

The bottom itself may also b e adjusted vto slidably accommodate the vertical stub beam. At the upper end of the boss 44 one iside of the said slot is leftopen as shown at 45, in vorder to make room for the head 46 of a bolt 47 by which the stub beam may be securely clamped in the box. The ends of the boxes are drilled or cored to provide horizontally and transversely extending apertures 48 accommodating bolts 49 which I extend through the upright flanges of the angle members 33 and 34. By reference to Fig. 7 it will be observed that the apertures 50 in the said vertical lianges of the angle members 33 and 34 are spaced at regular distances along the angle members so that-it will be unnecessary to drill additional holes whenever it is desired to eil'ect a change in thespacing of thebeam boxes. ,lVhen the spacing Vof the beams is to be changed itis not necessary to dismantle the plow, it being suliicient to remove thebolts 49 4vfrom theboxes whichare tovbe moved,

whereuponafter the bolts 2:35 and 36 are `slacked off the boxes vmay be slid along the guidi'ng'angle members v33and 34 tothe desired new location.

f `Referring now to the means for electing individual adjustment of the bottoms, it willgbe seenthatby reason of the stub beams ffhavingfvertical sliding engagementwith the boxesfor lhousings 39,40, 41 and 42, the bottomsmay be depressed orlowered'to suit y the varying conditions, it being understood thatthe upper ends of the stub beams 43 are made'with 4spaced apertures 51 to accommodate the clamping .bolts 47 at with` 'respect to itsl inclination to the stub 'beams Inthe present ,instance each botvvarious,

tom consists of a disk 52 mounted to rotate n a suitable axleV carried in the lower end of a cast socketI 53. Said socket 53 is formed with a pair of upstanding angularly disposed flanges 54 and '55,.as shown clearly in'Fig. 4. The vertical stubbeams 43 has `its end rounded slightly, as shown at 56 in AFi'gf, to rock in a recess or depression founded .by a lip 57 extending around the outer sides ot the said recess. The lower end of the plow beamis also `equipped with a pair of clamping bolts V58and 59 by which the said bottom be clamped to the longitudinally extending flange 54 ofl the socket. The upper bolt l58 extendsthrough azslot v60 in the upper. endof the flange 54 whereby the socket may bevrocked round a horizontal axis coincident withthe axis of the clamping bolt 59. In order to hold the socket in the desired inclined position without relying wholly upon the frictional clamping elect of the clamping bolt 58, I prefer to employ a substantial set-screw 6l threaded into the. other vertical ange 55 of the socket and bearing against the rear face of the stub plow beam 43 justy behind the clamping bolt 58.

It will be apparent from the above de scription of the parts thatthe construct-ion secures in an eliicient manner .the stated objects ot the invention in addition to which other advantages will be readily apparent kto those skilled inthe art.

The scope of the invention is not intended to be limited by the detailed-description of the parts but should be determined by reference to the appended claims, the latter being construed as broadly as possible'con sistent with the state of the art.

I claim as my invention:
